PY555 - Cosmological Physics - covers the basic theory underlying modern Cosmology. We will cover the geometry and dynamics of the universe, the thermal history of the universe, inflation, cosmological perturbation theory, structure formation, and the origin of initial perturbations from quantum fluctuations. The course will be based on the "Cosmology" notes by Daniel Baumann. For a lightning introduction to GR basics you may find Sean Carroll's "No-Nonsense" GR notes useful.
